If you apply some common sense, almost all scams can be detected easily, nothing is usually free. Yes I know giveaways exist out there but even those are ~ snip ~
Where you'll experience such ICO's scammed project is mostly in airdrops. They'll advise everyone (thousands of users) to send a particular amount of gas fee for them to send you their tokens or you've to have about 10 referrals before payment. By so doing many would like to invest and fall as a prey
airdrops are mainly free , they dont ask for a certain fee therfor you cant reall call it a scam . i also heard a kind of airdrop that ask to send 0 eth transaction but this arent also a scam because like i said earlier , you will only be sending 0 value transaction . its only for activation purposes i think . lastly , i also came across to an airdrop that requires invites and referall but they are also verified and not scam . scams oftenly occur on investing schemes and its hard to catch them so we must be aware and take time to ask for others suggestion before entering it yourself
Yes exactly. An airdrop cannot be a scam in it's self just because it doesn't pay. To scam you need to get something out of it and with airdrops they get nothing. Unless... The project runs airdrops they never plan on paying just so they can give their scam project one last push before it dies.
